Step-by-step explanation:
[tex] \sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Use the identity
[tex] \sin^2 \theta = \dfrac{1 - \cos 2\theta}{2} [/tex]
on the left side.
[tex] \dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Now use the identity
[tex] \sin \theta = \cos(\frac{\pi}{2} - \theta) [/tex]
on the left side.
[tex] \dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

A jewelry artist is selling necklaces at an art fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $12 each. The inequality 12n>135+4.50n represents the situation in which the artist makes a profit. Will the artist make a profit if she sells 15 necklaces? Show how you know.
Answer:
Step-by-step explanation:
12n>135+4.50n
12(15)>135+4.50(15)
180>135+67.50
180>202.50
False. They will not make a profit since the cost is 202.50 versus the selling price 180
Answer:no its not a profit

Peter says, "If you subtract 19 from my number and multiply the difference by - 7, the result is
- 140." What is Peter's number?
Peter's number is
Answer:
39
Step-by-step explanation:
His number is x.
"If you subtract 19 from my number"
x - 19
"and multiply the difference by - 7"
-7(x - 19)
"the result is -140."
-7(x - 19) = -140
Divide both sides by -7.
x - 19 = 20
Add 19 to both sides.
x = 39
Answer: The number is 39.

Greatest common factor of 25,50,75
Answer:
gcd (50; 75) = 25 = 5^2:
Step-by-step explanation:
hope it help
The greatest common factor of 25, 50 and 75 is 5*5, which is equal to 25.
We are given that;
The three numbers = 25, 50, 75
Now,
The greatest common factor (GCF) of two or more numbers is the largest positive integer that divides evenly into all the numbers with zero remainder.
To find the GCF of 25, 50 and 75, we can use the prime factorization method. This involves writing each number as a product of its prime factors and then finding the common factors among them.
The prime factorization of 25 is 5*5
The prime factorization of 50 is 2 x 5*5.
The prime factorization of 75 is 3 x 5*5.
The common factors of 25, 50 and 75 are 1 and 5*5.
Therefore, by factorization the answer will be 25.

can someone plz help i need to graph it and identify the x-intercept
Answer:
(-7/2,0) is the x intercept
Step-by-step explanation:
1. y+3 = -6/7x
2. -3 -3 ....subtract 3 from both sides to isolate the variable y
y= =-6/7x -3 ....is your new equation
You graph it by putting your point on negative three and then counting 6 units down and 7 units right.
For the x intercept you set y to 0 and solve for x
0= -6/7x -3
+3 +3 ...to both sides
3= -6/7x .....divide both sides by -6/7
-7/2=x
put it in as a coordinate

Answer:
Measure of angle T is 67.5 and measure of angle V is 22.5
Step-by-step explanation:
Solve for x
All the angles in a triangle equal 180
So,
3x + x +90 is 180.
Subtract 90 from both sides
3x+x = 90
Add like terms
4x = 90
Divide by 4 to solve for x
x = 22.5
Now substitute 22.5 in for 3x and x
Measure of angle T is 3(22.5) = 67.5 and measure of angle V is 22.5
Tom fed the dog 3 times as many times as her sister last week. His sister walked the dog 9 times. Max said he could multiply 4 times 9 to find out how many more times he walked the Dog than his sister. Is Tom correct?
Answer:
No
Step-by-step explanation:
The calculation that Tom is trying to do would be to calculate how many times he walked the dog if he had walked the dog 4 times as many times as his sister, who in this scenario walked the dog a total of 9 times. Since, in this scenario there is no mention of how many times Tom walked the dog then this calculation cannot be made and I would say that Tom is not correct.
